You don't have to give your data to social media companies, you know. That's just part of the trade off in using their apps.
Me making a comment on social media: anyone can can redistribute it, they could even charge money to read my comment if they'd like.
Disney playing Frozen 2 in the airplane in-flight entertainment system: I'm not allowed to copy, reproduce, distribute, or disseminate it.
